Hey - you can accept phone calls on your watch from regular landlines or cell phones. However, amazingly you CANNOT accept FaceTime audio calls or make them on your Apple Watch. That sucks. You can ask Siri to FaceTime audio someone on your Apple Watch but then it asks you to use Handoff to push the call to your iPhone. I can't wait until you can make and accept FaceTime audio calls ON the watch. It's so odd that it can make and accept calls from FaceTime - Apple's own medium. I'm just mentioning this because I've watched a MILLION reviews on the watch and read many and oddly enough not once was this mentioned.
